Exercise 3 Page 87

To find the area, calculate the product of the base and the height.

144cm^2

Practice makes perfect

The area of a parallelogram is the product of its base and its height. In the given parallelogram, we can consider the side whose length is 9 centimeters at the base and its corresponding height is 16 centimeters.

We can substitute these two values into the formula for the area of a parallelogram and simplify.

A=bh

b= 9, h= 16

A= 9( 16)

Multiply

A=144

The area of the parallelogram is 144 square centimeters.
